Antioxidant properties of desferrioxamine E, a new hydroxamate antioxidant

摘要

Antioxidant properties of desferrioxamine E, a cyclic trihydroxamate produced by microorganism, were A tested and compared to those of desferrioxamine B and butylated hydroxyanisole (BHA). Desferrioxamine E exhibited significant antioxidant effects in linoleic acid emulsions as well as in emulsions of linoleic acid and beta-carotene. In concentrations of 100 ppm, the effect of both desferrioxamines in linoleic acid emulsion was equal to that of BHA. The antioxidant activity of the desferrioxamines in emulsions of beta-carotene and linoleic acid was significantly higher than that of BHA. In addition, the initial rate of beta-carotene destruction was significantly lower when desferrioxamines were added to the emulsion. [References: 20]
